Hi there,
We have developed a main process with some sub processes in it. All tasks have a "self service"-assignment rule. Now whenever somebody grabs an unassigned task which is the first task of a sub process, the task has a new case-number.
Is there any possibility to use the case-number from the main process throughout the hole case including all sub-tasks?

Set this trigger to fire when the case is created in the properties of the process or before the first step in the first task if using an older version of PM.
Then, right click on the first task in the subprocess, and select Properties in the context menu. In the Activity Properties dialog that opens, go to Case Labels > Title and set it to: #@#parentCaseNo

Now the title of the subprocess case should be set to the number of the parent case.
